My new to me 1991 300CE was 100% dealer service by the PO. I assume that the pads are OEM. I really like the feel of the brakes though of course hate the dust. In between washing the car, I've opted to regularly dust the wheels with a soft bristle short handle brush. Takes all of 2 minutes. Doesn't make the wheels spotless but makes them a heck of a sight better with little effort.
